Cylindrical Handle Dynamometer for Improved Grip-Strength Measurement

CDC researchers have developed an improved dynamometer device and method for measuring maximum hand grip force or grip-strength. Human test subjects were used in conducting experiments to evaluate the handle and to assess the measurement method. In contrast to the currently used "Jamar handle" grip strength dynamometer devices, the cylindrical handle proved to be able to determine the overall grip strength for a subject, as well as show the grip force distribution around the circumference of the handle. The cylindrical dynamometer handle is accurate with less than 4% error, and it demonstrates that the measurement is independent of the loading position along the handle. For real-world applications, the device can be used to help diagnose the musculoskeletal disorders of the hand, monitor the recovery progress after hand surgery or injury, and collect grip strength data for tool and machine design.
